I have the following function:
func (s *SimplePeerConn) Read(b []byte) (n int, err error) {
ctx := context.Background()
var maybeCancelFn context.CancelFunc
func() {
s.deadlineLock.RLock()
defer s.deadlineLock.RUnlock()
if !s.readDeadline.IsZero() {
ctx, maybeCancelFn = context.WithDeadline(ctx, s.readDeadline)
}
}()
if maybeCancelFn != nil {
defer maybeCancelFn()
}
return s.ReadWithContext(ctx, b)
}
And I'm getting a possible context leak when I assign maybeCancelFn. I
originally had context.WithCancel and then overwrote the cancelFn in the
inner func.
How would I idiomatically rewrite this to not see the vet error?
